Abstract: A bandwidth part processing method includes receiving, by a terminal, a first information and a second information from a network device. The first information indicates that at least one default bandwidth part (BWP) corresponds to at least two active BWPs, the second information indicates that the at least two active BWPs correspond to at least one first timer, and the at least one first timer is useable by the terminal to perform deactivation processing on at least one of the at least two active BWPs. The method further includes performing, by the terminal, deactivation processing on the at least one of the at least two active BWPs, and activation processing on a BWP in the at least one default BWP based on the first and second information, or performing deactivation processing on the at least one of the at least two active BWPs based on the first and second information.

Abstract: The method is applied to a communications system including a first network device, a second network device, and a terminal device. The terminal device is communicatively connected to the first network device and the second network device respectively. The method includes: sending, by a network device, a first message to the terminal device, where the first message is used to determine that the terminal device stops communication with the first network device, or the first message is used to determine that the terminal device releases a protocol stack and a data radio bearer that are corresponding to the first network device; and the network device is the first network device or the second network device. Therefore, power consumption of the terminal device or the first network device and waste of air interface resources can be reduced, and flexibility can effectively be improved in a communication process.

Abstract: When cell system information changes, a first terminal device receives, during on duration of the first terminal device, system information sent by a second terminal device, so that the first terminal device can receive the system information through a sidelink between the first terminal device and the second terminal device without a need to maintain a cellular link, thereby reducing complexity and power consumption of system information transmission. Alternatively, when cell system information changes and a first terminal device has only one receive radio frequency chain, the first terminal device obtains system information within a gap period of communication between the second terminal device and the first terminal device through a link between the first terminal device and a network device, so that the first terminal device maintains a cellular link only within the gap period, thereby reducing complexity and power consumption of system information transmission to some extent.
